i want to install ios 8 to my iphone 4. how can i update

If you need to be running iOS 8 or above, you will need to replace your obsolete iPhone with a new one.

Nothing has changed since the first reply on this thread, you can't.

If your phone is an iPhone 4 it cannot be updated beyond 7.1.2.

This is never going to change.

I want a million dollars. Guess what? Neither of us is going to get what we want just because we want it. Buy a phone that isn't over 8 years old....

Please update my iOS 8.0

It is not possible

If can't if it's an iPhone 4

That's right. Because you have an old phone. You would have to get an updated one to run the most current version of software, or make do with what you have.

No

Time for a newer phone

Replace your obsolete iPhone 4 with a new one.

You can purchase a new phone that is capable of running iOS 8.

Please read the 54 pages in this thread that explain why you can't.

You may be able to get compatible versions of Apps. In iTunes on your computer, download the App you want a compatible version for using the same Apple Id that the iPhone has for the App Store. For Paid Apps its best to consult with the App maker to make sure there is a compatible App. With the App Downloaded to iTunes on a computer you can go into The App Store App on your iPad, Tap on Purchased, and Look for the App there. Tap on it to begin the download. It will likely say its not compatible, but if there is a compatible version it will offer to download it.

Install an app on an earlier version of iOS or OS X - Apple Support

Note that this option will likely stop working in the near future.

Yes. Why they post such junk here I don't understand.

I think there's a point you can get early on for posting a picture. As to why they're so often sideways, that is a mystery to me.

Can you explain to me why you made that post? Did you read any of this thread before you posted? Did you read at least the "Apple Recommended" answer before posting?
